Abstract :
A stable planar Gunn diode dielectric resonator oscillator (DRO) is reported at 31.4 GHz. The design is based on the measured impedance of the diode under large signal RF excitation. A six port reflectometer is used to measure the device line of the diode under test and the optimum point of operation is defined. In order to realize stable operation a dielectric resonator is used as part of the output matching circuit. The oscillator is realized in MIC technology and shows a 3.8 mW of output power at 31.4 GHz
